I've been calling it "long term traveling". I'm in Kuala Lumpur for about 2.5 months, then I'm heading to Chiang Mai for ~2 months, then to Phuket and Penang for a couple months, and then home (US). If you're going to SE Asia or you're interested in the area at all, I would absolutely recommend putting KL on your list! It's beautiful, and extremely culturally diverse, not unlike some cities in the US. And it can't be overstated how good (and cheap!) the food is.
What's on your radar right now for destinations?
